Rating: 5/5Awesome serviceAugust 19, 2019I bought one pair and it wouldn't work in my 2017 iMac. OWC returned them, tested them, replaced them and the new set works as intended. Thanks for the fast turn around and professional service

Rating: 5/5OWC MemoryApril 3, 2019I've use OWC memory upgrade kits in the past for all of the Macs that I have had. Never had an issue . Just put in a pair of 8 GB in my 5K iMac and it showed up right away after the startup.

Rating: 5/5Other World Computing Comes Through Again!November 20, 2018My one year old iMac needed a boost in memory (as do I-but that's another story). I used the Chat window, 'chatted' with a knowledgeable tech, asked a few questions and then ordered my memory chips.

They arrived two days later and thanks to OWC videos, my new RAM was installed, EASILY, in under 3 minutes!

I've purchased several products from OWC over the years and they just always come through with great deals, great videos and great technical assistance if you need it. Thanks, OWC!!!! 5 stars, as usual! :-)

Rating: 5/5Life ChangerNovember 20, 2018The memory upgrade I purchased from Other World Computing/MacSales.com allows me to work at 64 samples without audio clicks and pops. As a composer this allows me access to percussion VSTi's and integration with fantastic computer based hardware that previously were unusable due to latency issues at a 128 sample rate. Considering the time and money I have invested in programs and gear this upgrade was for me a life changing experience. Overall my whole system is more solid and fluid. It is as if the i7 processor was built to utilize the full memory capacity of my machine. Installing was easier than I imagined. I popped out the 4x8 GB PC4-19200 DDR4 2400MHz SO-DIMM's and installed the 4x16 MG PC4-19200 DDR4 2400MHz SO-DIMM's and my machine booted right up and showed the new memory in the system. Immediately I could see the power of the increased memory with the speed at which I opened programs, even my mouse seemed to glide more fluidly. And when I started using my software I knew I had made a wise investment. I do not recommend taking chances buying CPU intensive programs without having the memory to handle it in the first place, but upgrades in Mac's happen fast and programs are eager to use the extra processing power. Increasing memory is one of the best ways to get more out of your machine. As it stands now with new Mac's I believe it is the only upgrade possible. Thanking MacSales.com for increasing my workflow and opening the door to some fantastic possibilities.

Rating: 5/5So far, terrific!November 4, 2018I purchased 2 sticks of RAM for my Mac a few weeks ago. Good price, well packaged for delivery. Installed without a hitch and so far, so good. Machine is way faster, and the entire process of buying and installing was very easy. I've never ordered from OWC before, but it was recommended to me and I would purchase from them again.

Rating: 5/5Performs Perfectly!September 2, 2018Installed the 4 DIMMS into my new iMac with no issues. I've experienced none of the quirky system issues that are normally associated with RAM. This memory has performed perfectly!

Rating: 5/5Don't panic after installing your RAM!August 20, 2018I just bought a new 27" iMac 5K and added the OWC 32 GB RAM kit to it before I even plugged it in. The process is very quick and very easy -- it took maybe two or three minutes. No problem -- but be aware. The machine would not turn on when I first plugged it in, so I looked up the symptoms on my phone and was relieved to discover that it's normal. Newer Macs have to initialize any RAM when it is first installed or the RAM configuration is changed. I just followed the recommended routine -- unplug the machine, hold down the I/0 button for at least ten seconds, then plug it in and hold the button in again until it starts up. Everything boots properly and you're off and running. As I don't buy new Macs often, I was unaware of this change. But panic averted, I have a new machine with plenty of RAM and everything working just the way it should!

Rating: 5/532.0GB OWC Memory Upgrade Kit for iMac 27" 2017 with Retina 5KJune 6, 2018First of all, I have been a Macsales customer since 1990's. Everything I have purchased from them worked perfectly. I have a new iMac 27" 2017 5K w/ 3.4 processor. Like all iMacs it came w/ 8GB stock memory which is not adequate to run today's software. So, I purchased 32GB upgrade (2x16). Now I have a total of 40GB memory (32+8=40). It is a good idea to get two 16GB's because if you need to upgrade it to 64GB maximum in the future you can add just another pair of 2 x16 memory! Installation was really easy. Just unplug your iMac, put it on a soft surface screen face down. Press the memory cabinet cover pop up button down, slide in your new memory sticks, power up your computer and you're done. Note that you need to press the button really hard in order to pop up the cover. I used wood chopsticks to not to scratch my computer. Also, make sure to slide your memory in a correct way. It should be firmly in place and should not move. Today is my second day after upgrade and I am very happy w/ awesome performance.

Rating: 5/5No Brainer!May 1, 2018I honestly feel this is a no brainer! I boosted my iMac from 8Gb to 16Gb with 2X4Gb chips from OWC. I then decided it was necessary to just get a 32Gb set to boost to 40Gb. I do not regret this one bit and my iMac flies! Don't waste money buying the ram from Apple! I'm almost tempted to get another 32Gb from OWC and just max out the iMac.
